One friend reports that when kids are chatting/whacking each other, a co-teacher will have the kids stand up, open their mouths, and grab their ears...for 5 minutes, 10 minutes, whatever it takes.
Another friend tells me about a student who was acting up in class. She was sent to the teachers office and told to put a highlighter in each nostril and stand there for the rest of the class.
The most amazing thing to me is the kids actually did it. I can not imagine what would happen if a kid was told to do this in the US. After the mutiny, I am guessing the parents would have something to say, but here kids comply.
